Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F822CS is determined by strict equivalence across the following critical parameters: resistance value (8.2 kOhms), tolerance (±1%), package type (1206 / 3216 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

The substitute parts listed below meet all these core electrical and mechanical requirements. Parts are grouped into two categories based on power rating:

Category A: 0.25W (1/4W) Direct Equivalents — AC1206FR-078K2L, CR1206-FX-8201ELF, CRCW12068K20FKEA, ERJ-8ENF8201V, RC1206FR-078K2L. These parts provide identical electrical performance and are suitable for direct replacement in applications requiring 0.25W power dissipation.

Category B: 0.75W (3/4W) Higher Power Rating — CRCW12068K20FKEAHP. This part exceeds the power rating of the primary component and is suitable for applications where enhanced power handling is required or beneficial, while maintaining all other electrical and mechanical specifications.

Engineering Selection Recommendations

For New Designs and Active Production: Select from parts with Active product status: AC1206FR-078K2L, CR1206-FX-8201ELF, CRCW12068K20FKEA, CRCW12068K20FKEAHP, or RC1206FR-078K2L. All five parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

For Automotive Applications: AC1206FR-078K2L, CRCW12068K20FKEA, CRCW12068K20FKEAHP, and ERJ-8ENF8201V carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs where this certification is required.

For Enhanced Power Dissipation: CRCW12068K20FKEAHP provides 0.75W (3/4W) power rating with pulse-withstanding capability, compared to the 0.25W rating of the primary part. This option is applicable when circuit conditions require higher power handling within the same 1206 package footprint.

For Obsolescence Mitigation: RC1206FR-078K2L offers the highest inventory availability (496,046 pieces) and maintains Active product status, making it a robust choice for long-term supply chain security.

Avoid for New Designs: ERJ-8ENF8201V carries a "Not For New Designs" product status and should be used only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts be used interchangeably with the RCS3216F822CS?

A: All substitute parts with Active product status (AC1206FR-078K2L, CR1206-FX-8201ELF, CRCW12068K20FKEA, CRCW12068K20FKEAHP, RC1206FR-078K2L) are electrically and mechanically equivalent for applications requiring 8.2 kOhms ±1% resistance in a 1206 package. ERJ-8ENF8201V is functionally equivalent but carries a "Not For New Designs" status. CRCW12068K20FKEAHP provides higher power rating (0.75W vs. 0.25W) and is suitable for applications where additional power handling is beneficial.

Q: What is the significance of the 1206 package designation?

A: The 1206 package (3216 Metric) is a surface-mount chip resistor with standardized dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). All listed substitute parts use this identical package, ensuring mechanical compatibility with PCB footprints designed for the RCS3216F822CS. Minor height variations exist between manufacturers (0.024" to 0.030" seated height) but remain within standard PCB assembly tolerances.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory compliance of the primary part.

Q: What is the difference between the standard CRCW12068K20FKEA and the CRCW12068K20FKEAHP variant?

A: CRCW12068K20FKEA is rated for 0.25W (1/4W) power dissipation. CRCW12068K20FKEAHP is rated for 0.75W (3/4W) power dissipation and includes pulse-withstanding capability. Both maintain identical resistance, tolerance, package, and temperature specifications. The higher power rating makes CRCW12068K20FKEAHP suitable for circuits with greater power requirements.

Q: Why is ERJ-8ENF8201V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy applications only. While functionally equivalent and currently in stock, new circuit designs should utilize parts with Active status to ensure long-term availability and manufacturer support.
